Scaling particles on both the x and y axis

Goodnight Games

Is there a way I can scale particles on both the x and y axis? I have objects that aren't perfectly square so everything is getting thrown off.

I don't know if this is anything like what you want, but I was curious so I made a demo: http://dl.dropbox.com/u/19602014/trail.zip.

just make the particle "image" the one u want, should work if u make it the right size

make the image transparent on the bottom 3 quarters so you can make it a big square again

You can change the self.size.width and self.size.height by a multiple to keep the ratio the same. Are you wanting to re-size graphics while editing your game file or during game play?

Oh wait, just saw "particles." Hmm... So you're resizing particles and they aren't scaling properly?

Basically I have a few blocks that are say 200px wide by 45px height. I want them to leave a small ghost trail behind them. If I change the size to 200px it's a huge square and 45 is a small square, so what I need is basically a rectangle.

I have a plan b which involves multiple systems laid out across the top but I'd like to avoid the memory drain.

I see what you mean. I can't think of a way except using Spawn Actor behaviors.

Ok thanks, plan B it is.

Yeah that might just be how I'm going to do it. It's either that or I'll make particle systems as big as makes sense then change the offset till it fills up the space.

@morphinegamingmachine Great idea!
